This is a page about flashing a custom device tree overlay onto the EEPROM of a Raspberry Pi for the Datawave Raspberry Pi Hat.
Requirements:
- Datawave Raspberry Pi Hat (Digi-Key part number 1857-1020-ND)
- Raspberry Pi
- eepromutils (GitHub - raspberrypi/hats)
From the Raspberry Pi command line
git clone https://github.com/CurtisWJohnson/Datawave-RPi-Hat.git
cd Datawave-RPi-Hat
***In order to do the following, you will need to use eepromutils.
Compile the .eep file. (This will provide a unique UUID number for the hat.)
sudo ./eepmake Datawave-rpi.txt Datawave-rpi.eep Datawave-rpi.dtb
Flash the .eep file to the EEPROM on the Datawave hat. This needs to be performed while pin 26 on the Pi is pulled low.
sudo ./eepflash.sh -w -f=Datawave-rpi.eep -t=24c32
Reboot the Pi
sudo reboot
